I'm glad you started the meds! And that you haven't had any side effects with them. If you start having side effects with the Plaquenil I was helped a lot by taking it at night, just before I got in bed, that way I slept through most of the nausea.
I would really encourage you to take what you read on the internet with a grain of salt. Remember that people are most likely to post or write things when they have had a bad day, not a good day. Lots of the "facts" on the internet are decades behind where medicine actually is today. I read some pretty scary statistics after I was diagnosed and when I asked my Rheumatologist about it he said those were the stats before we really new how to treat it. RA is treated much sooner today and the biologics have revolutionized the treatment and prognosis of RA.
Something that I've found helpful in working with my rheumatologist is to remember that he has been treating RA literally since before I was born (I'm only 26.) He's seen RA from the time when it wasn't treated until damage had already occurred to now when it is treated aggressively as soon as it is diagnosed. So he's seen the full spectrum of the disease and so I've learned to trust his opinion and his recommendations. If he tells me I'm doing well and he's pleased with where I'm at, I know that that is 26 years of professional experience talking. You need a rheumatologist you trust and who listens to you. The more you trust your doctor the better you will do. Open communication is very important!
Everyone that I've personally met who has RA, myself included, we're all doing very well and live very active lives. Attitude is a big part of dealing with the RA. You have to decide not to let it get you down and to not let it define you. So hang in there, I think most people do pretty well today. Be patient, the beginning is the hardest time but things do get better. Physically you will start to feel better and emotionally you will get stronger. Take things one day at a time and don't get ahead of yourself. I hope you continue to feel good!
